HUGH V.' BUTT, OF NORFOLK, VIRGINIA.

` Application inea March, s,

as mud` brought upbydredges, coal, water,

sand `and other material and kcapable y of beino'feasily and quickly dumpedand cleaned.

',Furtherobjects andV advantages willbe more fully described herein and specifically pointed` out in the' claims hereunto annexed recourse being had to ,the accompanying drawings forming apart of this specification in which Figure 1 is a planl of one end of a scow or V,floating vessel equipped with my apparatus.

Fig. 2 is a longitudinal section of one end of a scow showing end views of two of the cylindrical dumping bins or hoppers.

Fig. 3 is an enlarged end view of one bin or hopper and a section Yof the scow.

Fig. 4 is a part longitudinal section of one of the dump hoppers. Y n

Fig. y5 is a side view of the hopper rotat-y ing or'duinping apparatus, and

Fig. 6 is an'endfview taken on the line 1-2 in Fig. 5.

In the drawings likev reference numerals indicateV similar parts in all thev several views 1 is the scow, barge or float which is built to accommodate the hereinafter described mechanism or an ordinary scow in use may be altered to receive the same, as desired.

2 represents the top :surface or deck of the scow or float and 3 are watertight compartments or partitions extending, preferably, athwart the scow ror vessel, and by them are formed the vertical dump wells 4 reaching from the deck 2 through to the bottom of the scow and consequently below the water line 3, as shown in Fig. 2.

Over and partly within the wells 4, are placed the outer bearing and supporting rings 5 arranged crosswise over the wells or openings and are disposed in an upright position near each end thereof, as shown,

:Specification of Letters Patent.

Patented Dec. 6, i921 192il serial No. 449,440.

and held in place by the hereinafter lde- Both the rings 5 and 8 are held to the deck 2 of the scow by means of the bolts 12 passlngthrough the lower flange of the brackets 11 which are in turn riveted orbolted to the rings vand` 8.`

AIn Fig. 4, A13 is a segmental plate or' ring member forming, with the other ring `elements, achannel and is for the purpose -of removing the rollers 6 by taking off the plate and a similar arrangement may be resorted to in regard to thefmiddle rings 8, as desired.

The dumping cylinders, hoppers or bins 14 are usually made Lof plate steel or iron and have ends 15 and an open side 16, above the axis or horizontal center line thereof so that the endmembers 15 have the form of a circular plate with a segmental portionrey moved, as shown.

17 are channels formed into rings and are bolted to each end of the circularjhoppers or bins Y114 toform a track for the rollers 6.

As shown, the rollers 9 in 8 bear directly uponthe plates of the cylindrical bins or in any other convenient manner.

As an additional supportfor the bins 14,

I may use a short axle 18V working in a suitable bearing 19, Fig. 1, also a shortaxle 20' on the opposite end of the cylinders 14 and securedby a flange to the bin end members 15 and held for rotation by a bearing stand 21 of any'convenient height from the deck 2 and the said height will govern the distance ofthe opening or bin outlet 16 from the deck surface and may be flush therewithor above the same, as shown in Figs. 3, 5 and 6.

On the shaft or axle 20, and out-side of the the channel ring icoY bearing stand 21, there is placed a bevel or Y miter gear wheel 22 normally inmesh with the slidable bevel or miter gear 23.

The gear wheel 23 is provided with a sleeve or axial extension 24 furnished with a keyway partly cut in the sleeve and the shaft 25 for the lrey or feather 26 so that it may slide a short distance either to the right or left upon the main horizontal shaft 25 Which extends to any length according to the number of bins or hoppers that the scoW contains which is usually about six, though any nuinber may be used as desired.

The sleeve 24 is provided With a suitable circumferential slot into which there is loosely fitted a ring 27.

' The ring is provided With a pin 29 which is in turn placed upon the lever 28 having a fulcrum block 30 fastened to the decle2 and by which the gear Wheel 23 may be placed inv and out of engagement With the gear Wheel 22 so that any one or all ofthe binsor hoppers may be dumped, as desired` The shaft 25 is suitablysupported at both of its ends, one of the supports is an ordinary bearing, (not shown) and the other by ihe gear frame or housing 32, as shown in The left hand end of the shaft 25 is provided With agear Wheel 31 meshing with a pinion 33` on the shaft 34 Which in turn carries the gear Wheel 35 meshing with the drive pinion 36 on the shaft 37 and upon said shaft is a hand Wheel 38 on the outsideV of the frame or housing `32 by Which power ismultiplied when operated allowing one or more of the cylindrical bins to be rotated so as t0 dump their contents, as in the case With mud excavated by -dredges or any other material that is desired to dump overboard. `39, represented by dotted lines in Figs. 3 and 6, indicates a combing which may be placed around the bins `14 to prevent the wash of Water when the scow` is loaded heavily or is in a rough sea. y

lf it is desiredto dump the loadof the bins, for example, sand or ballast, upon the shore, `the entire bins with the rings 5 and 8 may be lifted out by a derrick or crane by` means of the slings 41 attached to the ueyes or rings 40 secured to the upper part of theV rings 5 in any suitable manner.

In order to lift the cylinders or bins 14 from the Wells in this manner, it is only necessary to remove the bolts12 from the bracket supports 11, Fig. 3,\and the caps of the boxes 19 and 21 when the gear Wheel 22 is out of mesh with the bevel gear 23.

I mayA use other gear means `for rotating the cylinders or bins 14, for example, the

i providing of segmental racks near or upon the rings 8 meshing with a spur gear Wheel on the shaft 25instead 0f the bevel gears, as shown.

Various changescan be made in the mechanical construction to suit Working ccnditions and requirements for which the invention is used.

f It will be seen that the bins or hoppers 14 act Iin themselves as independent buoyant means and though the scow or vessel may be stove in by a collisionthe same Would be prevented from sinking by theflotation of the cylindrical bins or hoppers.

The invention is therefore valuable on. ac-

count of the impossibility of itssinlring more particularly if the open sides or out-` lets 16 of the bins 14 are coveredby any suitable means. i 4

By my apparatus, marine insurance rates Would be decreased as the danger of the loss of ialuable cargoes would be very much lessene 'Another advantagey of my ,invention is that the bins maybe used for a varietypof cargoes, for instance, coal Vmay betransported on one trip, unloaded, the bins Washed out, rinsed and dumped and When dry may` bereloaded With salt, mixed freight, sand &c., on the return'trip, then used for Amud dredgedupby mud machines or dredges,`

again washed and dumped and used for any kind of cargo.

I claim: i

f1. A scovv having vertical dump Wells opene ing through the bottom,`bearing rings disposed partly Within the Wells and partly above `the same, and cargo cylinders rotatively mounted Within said rings. y

,2.2 The combination with a scovv having a series of Wells extending therethrough from the deck to the bottom, of Vcylindrical cargo bins "placed over and Vpartly Within. said Wells, gear means on saidcylindersfor rotating the same, a horizontal shaft having gear means thereon adapted to normally mesh with the firstlnamed gears, and lever operated means for disconnecting saidgearinv.' y

testimony whereof I have hereunto affixed my signature in the presence of two Witnesses.
